UNITED STATES PATENT OFFICE 2,509,641 massive TAPE DlSPENSER Herman H. Hiilmjer, omalilag l ebn, assignor to Better Packages Incorporated; a corporation or New York Application August 23, 1945, Serial No. 612,258 15 Claims. (01. 164-42) The present invention relates to the art of dispensing tape. i i

It is an object of the invention to provide a device for dispensing predetermined lengths of tape from a roll or co-i1 thereof. The invention is particularly applicable to the dispensing of pressure sensitive adhesive tape which is characterized by the fact that it adheres to a material upon pressure. Tape of this character may have a normally adhesive or tacky surface upon one or both sides thereof. One well known type (if such tape is that identified by the trade name Scotch, which inemqe's transparent cellulose film having a coating of clingable material upon one side thereof. The invention, however, is not limited to use with that particu lar type of tape. I i a As heretofore practiced, certain devices have been employed, such as that certain device shown and described in United States Patent No. 2,221,213, the mechanism or whieh facilitates a manual uncoiliiig of a roll of the said tape and a tearing of a length of tape from a coil thereof. However, during the use of said mechanisms, an operator usually pulls out from the 0011 too great a length whereby a large amount of tape is wasted and the present invention aims to pro vide a means whereby a predetermined length only may be withdrawn from a roll of said tape, said length being su'fiicient for sealing oppositely disposed edges of package papers together, whereby economy is practiced in the art of sealing bundles in stores and the like,

A further object of the invention'is to provide a device for conserving an operators time in sealing packages arid bu'ndles with said speeial tape since, as heretofore practiced, during an operation of the mechanism of the Patent No. 2,221,213, an operator would often tear off too short a length 6f tape from a roll for paper'sealing purposes, thereby necessitating 'a tea ring oif of a second strip with an attendant waste of tifne and material and the present invention aims to ebviere eertern other disadvantages of the prior practice,

Other and further dbjects and d anteges or the invention will be' obvio s from the following detailed description therebf.

In the drawingsi v V Figure 1 is a side viewer a tape severing and dispensing mechanism enibodying the present invention. V v V Figure 2 is a longitudinal vertical seeaen there: of, the new beifie taken eiibsteriuauy on line 2--2 of Figure 3.

Figure 3 is a top plan view of the mechanism shown in Figure 1.

Figure 4 is a side view of a portion of the new mechanism, the view being taken substantially on linfe 3-4 of Figure 3.

Figure 5 is a transverse vertical section of a portion of the machine and showing a tape holder roller emplo-yed,.the view being taken substantially 'on line 5-5 of Figure 3.

Figure 6 is an end view of the mechanism shown in Figure 1.

Figure 7 is a detail showing a slidable cutter o'r knife employed.

Referring now to the drawings for a more particular description, it indicates a base and II a wall or plate which is secured theretb by any suitable means such as welding or the like or formed integral therewith, whereby a support or frame is provided for the later described parts. Durinf; use, the plate H is approximately Vertic'all'y disposed since the base rests upon a counter, desk or the like. An enclosure housing, not shown, is] preferably employed and the major portion of the later described mechanism is disposed therein.

.The preferred embodiment of the invention shown in the drawings includes a roller for supporting a coil of tape thereon, a reel-wheel, an aetuating lever, a ratchet mechanism for connecting said lever and reel-wheel together, a knife or outter a means for causing said knife to sever the tape during a movement of the lever in one directionand a means for restoring the position of the knife and other movable parts to a normal position with respect to the frame and each other.

Referring to Figure 5, the vertically disposed frame plate H is provided with a stud bolt l2, the latter being disposed at a right angle to said plate. The bolt l2 provides an axle upon which a later described tape holder or roller is revolvably disposed.

'Ihe tape holder prerereuy includes a sleeve I3 pi 'v'otally mounted on the axle" l2. A disc l4 is enemy disposed on the sleeve l3 and prevented from movement longitudinally of the sleeve by means of a collar 15, the latter being preferably provided with a set screw it. i

The disc M is step-cut, as indicated at 11, for providing an annular shoulder for supporting thereon a later described roll of tape.

The outer end of the sleeve I3 is provided with Saree threads [8 and a second plain disc or plate I3 is threekiedlS en aged with the thread l8 bf the sleeve !3. As thus described, it will be seen that the plate l9 may be positioned closer toward the disc it or further away from said disc than is shown in Figure and for purposes later described. A set-collar 2!] is secured on the outer end of the bolt 52 by means of its screw 2|.

A coil of the particular type of tape which the mechanism of the present invention is particularly adapted to dispense is indicated at 22. The innermost convolution of said coil is disposed about a paper core, the latter being indicated at 23. The perimeter of the core is castellated being provided with alternate notches and ridges, the latter being indicated at 2A and the notches at 25 in Figure 1, and since said core is formed of paper and castellated, the latter is compressible.

Referring to Figure 5, the inner annular wall 26 of the core 23 rests upon the annular shoulder provided by the step-cut ll of the disc I4 and at times when the plate is is rotated upon the thread is against the core 23 of the coil, the oppositely disposed side walls of said core are squeezed between the disc ill and the plate E9 in a manner whereby the coil of tape 22 is rigidly secured to the roller while at the same time, the tape may be unwound readily from the coil. The collar 2i? prevents the plate 89 from moving away from the coil of tape 22 and the set-collar i5 positions the coil of tape and its roller longitudinally with respect to the sleeve l3.

It will be seen that a coil of tape of one-half inch width may be secured to the tape holder roller, the latter being generally indicated at 21, and that at times when it is desired to cause the machine to dispense tape from a coil of greater transverse width, the same may be readily consummated by causing the set-collar 2G and the plate is to be disposed further toward the free end of the axle bolt 52 than is shown in Figure 5 and complemental to the transverse width of the tape selected.

Referring to Figure 1, a second axle bolt 28 is employed having a shoulder 29 which is disposed at one side of the plate ii and a nut 89 at the other side of said plate for drawing the shoulder 29 against the adjacent side of the plate H, whereby the axle 28 is rigidly maintained at a right angle with respect to the plate H as best shown in Figure 6.

A reel-wheel 3! is revolvably disposed on the axle '28. As best shown in Figures 3 and 6, the reel-wheel is provided on the perimeter thereof with a plurality of equidistantly spaced apart fingers 32 which are radially disposed with respect to the axis of said wheel and extend from the latter at a right angle with respect to the plate H and transversely with respect to the roll or coil of tape 22.

The reel-wheel 3| is provided with a hub 33 which preferably is formed integral with the hub 34 of a ratchet-wheel 35. Also, if desired, the hub 33 may be locked to the hub 34 by means of a set-screw 36, as shown in Figure 6, whereby in operative effect, said hubs are integral.

As best shown in Figure 1, since the fingers 32 of the reel-wheel are disposed beyond the perimeter of said wheel, the outer edges of the fingers provide ridges indicated at 3'5 and the concavities 33 between said ridges for purposes later described.

The ratchet-wheel 35 is provided with a tooth for each ridge 3] of each finger 32.

It will be understood that since the said tape 4 is usually approximately transparent that the fingers 32 are visible through said tape as shown in the drawings.

One side of the tape is provided with a film of clingable material, said tape being known to the art as of pressure-sensitive type. The said material not only causes said film to adhere to said side of the tape, but also causes said film and tape to cling to substantially any extraneous substance or article with which it is placed in contact, more especially if a slight pressure be applied to said tape at that side of the latter which is oppositely disposed with respect to said film.

As thus described, it will be seen that, as shown in Figure 1, the film clings to certain of the ridges 3? of the reel-wheel during revolvable movements of the latter for unwinding the coil of tape from the core 23 since, as shown in said figure, said film is always in contact with a plurality of said fingers, whereby the amount of adhesion to said fingers is greater than the amount of adhesion of the tape to its coil.

Referring to Figure 1, since approximately five of the ridges 3? are in contact with the film of a strip of tape, the area of said five ridges or fingers being greater than the transverse width surface of a convolution of the coil 22, the latter is caused to unwind during revolvable movements of the reel-wheel since there is a greater surface for said film to cling to provided by the reel-wheel than the transverse width surface of a convolution of the coil 22.

An idler roller is preferably employed, especially in instances where tape of comparatively large transverse width is to be dispensed by the mechanism. The idler roller 38 is axially and revolvably disposed on a third axle bolt 39, the latter being disposed at a right angle with respect to the plate H and secured to the latter by any suitable means. The opposite ends of the idler roller 38' are respectively disposed between suitable detents such as the set-collars 40 and ii.

As thus described, it will be seen that at times when the reel-wheel is rotated in the direction of the arrow 58 that a corresponding movement is applied to the coil of tape for unwinding the latter, said tape becoming severed transversely in predetermined lengths by later described means.

The means for rotating the reel-wheel intermittently includes a lever 42 which may be provided with a handle 43 at its outer or free end. The inner end of the lever is attached by any suitable means to a carrier-plate 45 or may be formed integral with said plate.

As best shown in Figure 7, the carrier-plate 35 is revolvably disposed on the axle-bolt 28 and means are provided for limiting a swinging movement of the lever 42 in two directions, whereby the carrier-plate is reciprocably disposed on said axle-bolt 28.

As best shown in Figure 2, the carrier-plate 45 supports a pawl 46, the latter being secured to said plate by means of a pivot pin or screw 4?. A spring 48 is provided having one of its ends secured to said carrier-plate by means of a screw 49 and its opposite end is disposed against the pawl adjacent the free end of the latter for urging said free end into contact with the ratchetwheel 35 and more particularly into engagement with the teeth 56 thereof successively during revolvable movement of the ratchet-wheel in the direction of the arrow 58.

A detent or stop 5| is secured to the frame plate I! for limiting the movement of the lever 42 toward the bobbin or roller 21 which supports the coil of tape 22 and a second detent or stop 52 is similarly secured to the frame II for limiting movement of said lever in an opposite direction.

As best shown in Figure 4, an end 53 of a spring 55 is secured to the carrier-plate 45 by means of a pin or other suitable keeper 5 The other end 56 of the spring 54 is similarly secured by means of a pin 5? to the frame plate I l whereby the lever 42 is normally urged against its detent or stop 5|.

At times when the lever 42 is manually moved by the operator in the direction of the arrow 58 and against the stop 52, a corresponding movement is applied to the carrier-plate 45 for causing the pawl it to turn or advance the ratchetwheel 35 one or more teeth, depending upon the distance which the lever may move between the stops 5i and 52, whereby a corresponding movement is applied to the reel-wheel for advancing one or more fingers 32 or ridges 31 thereof correspondingly and for unwinding a corresponding length of tape from the coil 22. With the spacing of the stops 5| and 52 shown in the drawings, particularly Fig. 2, it will be seen that with each reciprocation of the lever the ratchet will be moved a distance of two teeth so that a piece of tape adhered to two of the fingers 32 will be severed and dispensed at each operation of the machine.

As soon as the lever 42 contacts with the detent 52, the operator releases said lever, whereupon the spring 54 returns the lever to a normal position against the detent 5| thereby causing the free end of the pawl 46 to engage the appropriate tooth 55 of the ratchet-wheel preparatory to advancing the successive fingers or ridges and by a repetition of the above described operation the device is manually actuated intermittently.

As best shown in Figure 1, a spring 59 is provided having an end secured to the base plate ID by means of a screw or keeper 60-. The free end of the spring 59 engages against the fingers 32 successively during a revolution of the reel-wheel for preventing a movement of the reel-wheel in a direction opposite to the arrow 58.

Means are provided for severing the tape during a movement of the lever 42 from its normal or full line position to the dottedline position thereof as shown in Figure 2. and saidmeans preferably includes a knife holder 6i which is slidably disposed with respect to the carrier-plate i5 and the lever 42.

As best shown in Figure 7, the member 6| is provided with an elongated aperture 52 through which the axle bolt 28 extends;

A pin 63 is secured to one side of the knife holder 5!, said pin extending through a second and. similar elongated aperture 64 formed through the carrier-plate 45 adjacent the junction of the latter and the lever 42, whereby the member BI is longitudinally slidable with respect to the lever 22 and is swingable therewith.

On that side of the knife holder 6! which is oppositely disposed with respect to the pin 63, a lug 55 is provided adjacent the end 66 of the member 5!. The lug 65 carries a screw or similar suitable keeper 51 for attaching a cutter or knife 62' thereto. Preferably, as specifically shown in the drawings, a safety razor blade is employed for the cutter 68',being attached to the lug 65 by the screw 6'! or in any other suitable manner. As best shown in Figure 7, the other endBS of During a return of the lever to a normal position,

the member BI is provided with a tang 10 which, as shown in Figure 6, is disposed at a right angle with respect to the main body portion of the member 5! and one end of a spring II is secured to the free end of said tang, the other end of said spring being attached to a pin 12, the latter being secured to the carrier-plate 45 and to the reverse side of the latter with respect to the member 6! as shown in Figure 4. The spring H normally urges the member 6| and the knife or cutter 68 toward the free end of the lever 42 whereby, as shown in Figure l, the knife 68 is normally disposed above the strip of tape preparatory to severing the latter.

As shown in Figure 6, the cutter 68 is preferably inclinedly disposed whereby during a later described tape cutting operation, the sharp edge of the cutter traverses the strip of tape transversely and progressively during a descent of the knife and with the result that the knife does not press against the tape unduly.

During operation at times when the several parts of the mechanism are in their normal position, as shown in Figures 1 and 7, and the lever 42 is swung in the direction of the arrow 58, the knife remains in a stationary position with respect to said lever until such time as the pin 53 carried by the lever contacts with the underside of a guide-plate or cam 13 and since the latter is maintainedin a stationary position, by a means later described, during a movement of the lever 42 in the direction of the arrow 58 and since, as shown in Figure 1, the guide-plate 13 is inclinedly disposed, the pin 63 is caused to become moved toward the axle bolt 28, thereby causing the knife holder 6i to become correspondingly moved together with the knife or cutter 58 and against the urge of the spring H, whereby the knife descends from its normal position, as shown in Figure 1, through the stripof tape for severing the latter, the operation being permitted since, as shown in Figure 1, the knife is disposed between two of the spaced apart fingers 32 for a descending movement into a concavity between two of said ridges during a movement of the knife in the direction of the arrow 58'.

Referring to Figure 4, the guide-plate or cam 13 is formed integral with anarm 14 and, as best shown in Figure l, the guide-plate I3 is disposed at a right angle with respect to the main body portion of the arm I4.

One end of the arm 14 is pivotally attached to the backing plate II by means of a pivot pin 15.

The end 16 of the arm 14 is attached to one end of a spring Ti, as best shown in Figure 2,

and the other end of the spring TI,- as best shown in Figure 4, is attached to the lever 42.

the lever 42 and its movement is limited in the said direction by means of a pin- 18 which is carried by the plate I l, as best shown in Figure 3'.

It will be seen that at times when the lever 42 is moved in the direction of the arrow 58 that the pin 63' engages the undersideof the plate 13 for causing the knife to descend and apply a severing cut to the strip of tape since said knife is progressively forced downwardly during a swinging movement ofthe lever in the direction of the arrow 58. I

Slightly before the lever reaches the endof its stroke and abuts the detent 52, the pin 53 disengages the underneath side of the plate I3 and the spring ll causes the knife, together with the pin 53, to move upwardly to its initial" position.

The spring 17 urges the end 16 toward the free end of ,2 the pin 63 moves over and against the upper side of the plate 73 and the latter becomes forced downwardly against the urge of the spring Ti since the urge of the spring M is greater than the urge of the spring ll, whereby during operation, the pin 63 slides off of the plate 13 to its normal position, as shown in Figure 4, and travels around the plate it once for each succeeding cutting stroke of the knife blade 68. It will be seen that the knife is completely returned to its initial position by the action of the spring ll before the return stroke of the lever begins, the knife passing upwardly between the cut ends of the tape. The knife thus is in position to clear the ends of the fingers 32 and the leading end of the unsevered portion of the tape, so that the oscillating lever is free to return to its initial position as soon as it is released by the hand of the operator.

During operation and assuming that the coil of tape 22 is disposed on its tape holder or roller, as shown in Figure 1, the free end 19 of the strip 85] of the coil 22 is threaded under the idler roller 38 (in instances where the latter is employed) and over a plurality of the fingers 32 and in contact with the ridges 3? of the fingers.

The lever 32 being manually moved in the direction of the arrow 58 causes the knife to descend as above described for severing the tape simultaneously with an advancement of the tape as caused by the reel-wheel, whereby a length of tape, indicated at 88, is severed from said end l9 and removably adheres to a ridge 31.

Further manipulation of the lever 42 for severing an additional length of tape causes the strip 86 to be disposed beyond the vertically disposed side edge 8| of the frame plate H and in an accessible position whereby the operator may dispose one of his fingers between two of the fingers 32 of the reel-wheel and under the severed length 8%? for removing the latter from the ridge to which it is clingingly attached during the delivery of said length to an accessible position for removal by the operator.

From the foregoing description, it is thought to be obvious that an adhesive tape dispenser constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason, I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as claimed.
